@Hugo: Nice post, I would argue that you would only probably see 5000 items on a single page is if there is a data table. So a better test case would have probably been TABLE elements like tr and td instead of P and SPANS, maybe DIVs.

But over all a really nice follow up. My post was only really geared to what I seem to do on a daily basis.

Hi Benjamin,

This topic is very interesting. I wrote an article that might complement yours. I created a big html page with over 20,000 elements and test more selectors. Comments from the community are always welcome:

@Brian: very true but would not have thought for one second the it would have been slower with firebug and faster with firebug-lite. Well, that does change things. I am going to have to reevaluate some of these numbers.

Thanks for that tip.

Always make sure you level the playing field as much as possible before making comparisons :)

Firefox+Firebug:
6.1: 113ms
6.2: 103ms
6.3: 105ms

Firefox+Firebug lite:
6.1: 32ms
6.2: 7ms
6.3: 8ms

@Andy: I think I did not finish my thought with the “I’m a little shocked…” statement, the jQuery team has been very up front about it being optimized for IE. Every time that “SlickSpeed test” pops up in conversation on the mailing list, that point is stressed.

My ending thought was that I am shocked that firefox was so slow compared to the other browsers, yes, we are talking milliseconds, but the point of the post was to find the fastest.

My other thought is and I think shocked is probably to strong a word for it, surprised maybe, but in test 6 line 2 and 3 are faster in all browsers compared to line 1 and that goes against some of the advice and discussions that were had when I got started with jQuery back version 1.1.

It’s not as big a surprise as you think. The jQuery team has been up front about the fact that the library is optimized to run more effciently in IE.
